OP

It was very lengthy. i mean there were 7 questions as usual but the questions themselves took me too much time to think e.g. the machine shutting down question and question 5 of tree diagram.

I found it okay
Just a normal paper, except for the very last question, which I personally could not solve
Even got 15 minutes in the end)

What were your answers, guys ?

Fairly easy paper. Didn't had any problems except for the 1st question on histogram. Expecting average grade boundaries.

Answers to which question? And what was the last question about, I can't quite recall it.

You had 15 mins left at the end or were given 15 mins extra?

To all questions that you remember

Surely I just had them, no one would give me 15 additional minutes

The question about discrete random variables

Haha I can't remember any, other than the histogram question.

Regarding the question about the probability of the machine being shut down, does "within 4g of the mean" mean that the weight was maximum 4g more than the mean or did it mean that the weight was either 4g more than the mean or 4g less than the mean? I would be grateful if someone answered!

You had to find the probability that its either less than or greater than the mean

if the mean was 20g then this would be "between 16 and 24g"

what was the answer for P(Y=X)

Wasn't it Y=X^2? Anyway I can't remember the answer completely but I believe it was 0.3 something. Perhaps I will remember it if you could tell me some bits of that question.

Hi guys. What do you reckon the grade boundary for an A will be this time?
